Improvement in vapor-burners



` UNITED STATES PATENT OEEICE;

THOMAS s. GATES AND A. H. EEITOHEY, OF OOLHMBUS, OHIO.

IM PROVEM ENT IN VAPOR-BURNERS.

Speeication forming part of Letters Patent No. 93,698, dated August 17,1869.

To all whom it may concern:

Be it known that we, THOMAS S. GATES and A. H. FRITCHEY, both ofColumbus, in the State of Ohio, have invented an Improvement inVapor-Burners; and we do hereby declare that the following, taken inconnection with the drawings which accompany and -form part of thisspecification, is a description of our invention sufficient to enablethose skilled in the art to practice it. v

This invention is an improvement upon that for which we obtained LettersPatent June 1, 1869, and numbered 90,659, and in which a supplementalburner or orifice from the chamber of the main burner formed acommunication or passage from it to a vertical tube attached to the sideof such main burner, the supplemental burner serving to facilitate andhasten the generation of gas from the iiuid in the supply-pipe, fed froma vessel or fount, sufficiently elevated, in a manner well known. Inthat patent the auxiliary burner or orifice formed a directcommunication or passage from the main burner or gas-chamber, (marked Bin the accompanying sectional drawing, forming part of thisspecificatiom) to the vertical tube, marked E, and at a point above thegenerating-chamber G.

While that novel construction has been found to be a successful andimportant improvement, and to answer admirably all the purpose for whichit was devised, we find, upon further experience and study, that we gainmany decided advantages by dispensing with any opening between the partsB and E, and, instead thereof, making the opening from E directly intothe generating-chamber G.

Incidentally to this change in the construction, we also make the smallpin-hole or communication F between the generating-chamber G andthegas-chamber B smaller than heretofore, and also the opening C smallerthan the opening between B and E in the above-named patent.

The other parts, A, D, and H, are substantially the same in constructionas in said patent, A being the ordinary slit for the exit of the gas forilluminating; D, the opening to admit air into the gas-chamber of theburner; and H, the tube, to be' filled with cotton or other appropriatepacking to regulate the iioW of the liquid from the reservoir.

The hole G we prefer to make about the size of a No. 14 needle, and,notwithstanding this diminution in size, we nd it is not liable to bechoked up, inasmuch as the force of the gas, coming as it does directfrom the generating-chamber, proves alwayssuflicient to keep it open andclear.

The following advantages result from the above-described improvedconstruction: First, the auxiliary jet C being nearer the first chambersupplied from tube H than it was in our former construction, and thischamber G being a much smaller one than B, and being more nearlyinclosed, and having no large'airhole like D, such jet, as above stated,can be made very small, and yet give all the heat required to generate asufficiency of gas for the illuminating-burner. Second, there is nopossibility of smoke from this heating-jet, both because of itsminuteness, and of its distance from the top of tube E. Third, the llameof the heating-jet cannot rise high enough to be vis' ible above the topof tube E, and consequently cannot interfere with theilluminating-flame, as to direction or otherwise. Fourth, it allows fullforce to the illuminating-flame, and does not cause any waste byimperfect combustion, thereby affording a fuller iiame and yielding morelight, even with the same sized pin-hole at F.

The reservoir should be about six inches above the level of the top ofthe burner, and

l"should preferably be supplied with benzine or petroleum iiuid of about7 0 gravity.

We claim-f In a vaporburner provided with an auxiliary vertical tubeopen at both ends, and with an orifice, serving as an auxiliary jet forheating, the making of such orifice so las to commimicate directly fromthe generating-chamber G to the vertical tube, as and for the purposedescribed.
